Divide each side of equation by 1/3. This will leave you with ?x1=10 divided by 1/3. When you divide with a fraction you have to invert it which gives you 10x3/1=10x3. This leaves you with ?=10x3. ?=30. Proof: 30x1/3=10. Hope this helped.

Column 75" tall, 16" wide and 16" deep. How many sq feet of stone to cover the column and top?

you have a rectangle of of 75 X by16 and you have 4 of those rectangles so multiply 75 X 16 and then multiply the sum by 4
then you have the ends which are squares of 16 X 16 so multiply 16 X 16 Nd then multiply the sum by 2
then add the 2 sums together to get the total square inches of the surface of the object
now one square inch =.00694 square feet so multiply the total sum by .00694 to get the area in square feet

What are the formulas in grading the grades uisng microsoft excel

Formulas are used to specify calculations based on values in designated cells. Excel supports basic calculations as well as statistical, trigonometric and other specialized functions.

Formulas used in Excel must follow a certain syntax.

  1. All formulas begin with an equals sign (=).
  2. Some formulas use operands such as +,-, *,/ for addition, subtraction, multiplication or division.
    For example, the formula =A1+A2+A3 would add the contents of cells A1, A2 and A3.
  3. Other formulas refer to different functions such as SUM, AVERAGE and others.
    For example, the formula =SUM(A1:A3) would add the contents for the range A1 through A3.
  4. Formulas can be combined with operands.
    For example, the formula =10*SUM(A1:A3) would add the contents cells A1 through A3 and multiply them by 10.
  5. Functions can be nested within each other.
    For example, the formula =SQRT(10*SUM(A1:A3)) would take the square root of ten times the sum of cells A1 through A3. When functions are nested, it is important that the number of left parentheses match the number of right parentheses.

Can this calculator find the sum of two rational expressions??

All calculators can calculate the sum of two numerical expressions (no letter symbols).
To be able to declare that this calculator can add two rational expressions ( with letter symbols or not) and displays them as a rational expression (result) I would need to know the EXACT Model.

Can i do sigma notation on a ti-30xa calculator?

No. There are some keys on the TI-30XA that may make you think so, but they are statistical operations. For example, you can enter values using the Sigma+ key and the TI-30XA can give you the sum of the values entered, sum of the squares, mean value, standard deviation and so on.

You cannot do calculations like "Give me the sum of all integers from 1 to 100" with the TI-30XA, you'd need a far more sophisticated calculator.

How do I calculate the standard deviation on an Aurex Prestige calculator?

standard devition is easy once you get your head around it for grouped data you have to take the equation apart so put in the sum of f then bracket (x-mean) squared and then divide by the sum of f and square root everything on the calculator. And then for non-grouped data you need to do the sum of (x-mean)squared then divided by the sum of n and once again square root everything.
Hope this helps
Good Luck
